Definitions

  • commercial vehicle compressed air treatment systems with two (or more) air drying cartridges which can be operated alternately in supply and regeneration mode, ensuring a continuous compressed air supply from the compressor via the air drying cartridge operating in supply mode.
  • the dried compressed air flow from the outlet side of the air drying cartridge operating in supply mode is divided into a partial air flow, which is then fed to the downstream compressed air system, and a partial air flow that is used as regeneration air flow and flows in the opposite direction through the other air drying cartridge operating in regeneration mode to ensure regeneration mode.
  • a partial air flow of the compressed air flow delivered by the compressor is available in the compressed air system during the entire operating phase of the compressor.
  • Commercial vehicle compressed air treatment systems with two air drying cartridges are also known as "twin towers.” The use of a twin tower may eliminate the need to activate and deactivate the compressor, which can simplify its control and/or increase its service life.

  • An air drying cartridge is arranged in each of the two line branches.
  • the line branches each have check valves opening in the supply direction, which are arranged downstream of the air drying cartridges. with a bypass line bypassing the check valve, in which a throttle is located.
  • a vent valve alternately controlled by the 4/2-way solenoid valve, is arranged upstream of each air drying cartridge. Due to the pneumatic control by the electrically controlled 4/2-way solenoid valve, the vent valve in the line branch in which the supply is established is shut off, allowing compressed air from the compressor to flow via the pressure regulator and the shuttle valve, via the air drying cartridge of this line branch, and the check valve to the central line.
  • the vent valve in the other line branch must be opened via the 4/2-way solenoid valve for the purpose of regeneration, so that a partial air flow from the other line branch, which is in supply mode, can flow backward through the air drying cartridge in the line branch in which regeneration takes place via the bypass line and the throttle, with the moist compressed air escaping into the environment via the vent valve.
  • Alternative embodiments disclosed in this document are dedicated to the reversal process for using a line branch for supply mode for use in regeneration mode and vice versa. It is proposed to arrange a dual-pressure valve parallel to the shuttle valve arranged on the inlet side of the line branches, the output of which is connected to the 4/2-way solenoid valve.

  • the document proposes designing the throttle valve with a continuously variable throttle, wherein the change in the throttle characteristic is controlled pneumatically.
  • the delivery pressure provided by the compressor serves as the control pressure.
  • the non-genre publication GB 352 972 A discloses a compressed air system for locomotives and other vehicles in which air flows through two adsorbers or containers in parallel pipe branches. Air drawn from the ambient air and heated by a heating device can be used to dry and reactivate the material in the adsorber. The air flows through the adsorbers are controlled via manually operated valves located upstream and downstream of the adsorbers.

  • the invention is based on the object of proposing a commercial vehicle compressed air treatment device with improved possibilities for controlling or utilizing the compressed air flows in a load operation and/or regeneration operation.
  • the present invention breaks away from the prejudice of the expert that It must be noted that for the desiccant to regenerate, the load operation must be interrupted, which is the case for commercial vehicle compressed air treatment systems with a single air drying cartridge and entails complex measures to optimize and minimize the regeneration phases.
  • the invention does not follow the prejudice that by eliminating the mandatory interruption of the load phases by using two air drying cartridges in a twin tower, optimal pneumatic compressed air flows are provided for the compressed air system downstream of the air drying cartridges, by alternating flow through the air drying cartridges in supply mode and in regeneration mode.
  • the invention proposes that, in a compressed air treatment system with two air drying cartridges, the regeneration operation of one air drying cartridge be controllable independently of the supply operation of the other air drying cartridge.

  • the invention encompasses the digital change of the pneumatic connection from a blocked position to a flow position and vice versa, as well as any other change to the pneumatic connection, in particular a change in the flow rate.
  • Instructions on how to determine the time to initiate and/or terminate regeneration operation in an air drying cartridge, as well as the required time duration for regeneration or regeneration air flow, can be obtained by the expert, for example EP 0 808 756 B2 These measures can be taken into account when controlling the required connections of the air drying cartridges. Another method for determining a suitable regeneration time is described in EP 1 390 244 B1 revealed. Further measures for determining the volume of compressed air passed through an air dryer cartridge, the time of regeneration, the volume of air required for regeneration and the time to end regeneration can be found in particular in the publications EP 0 093 253 B2 and WO-A-91/16224 known.

If, however, the control port of the 3/2-way valves 17, 18 is pneumatically actuated, thereby switching the 3/2-way valves 17, 18, the 3/2-way valve 17 connects the air drying cartridge 15 on the inlet side to the vent port 6a, while the inlet port of the air drying cartridge 16 is connected to the partial inlet line 7 via the 3/2-way valve 18.
